Fire, Ice and Lightning is a secret boss in the special mission Wizard Lord. If you complete Wizard Lord with just Monkey Apprentices, (Hint: You can sell all non-Monkey Apprentice towers at the last second) the screen will freeze (literally - it will be stuck in a block of ice), get struck by lightning and then burn up. It will then reform, your Wizard Lord will still be there but all your tower's will be refunded at full cost and you will get a $50000 cash injection. You can then now prepare for the upcoming boss fight: (Note: The bosses are bloons, not blimps)
